SNOW OR DIRT COLLECTING AND DUMPING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 572,213, dated December 1, 189E I Application filed A ril 5, 1895. Serial No. 544,540. (No model.)

To all whom) it may concern:

Be it known that I, CARL GUSTAF OTTER- STEN, a citizen ofthe United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Snow or Dirt Collecting and Dumping Machines, of which the following is a specification.

- My invention consists of improvements in apparatus to be moved along the street on wheels .or runners and having a scrapingscoop and a rotary brush at the front for 001- leeting snow or dirt into a box behind the scraper and also having means for dumping the loaded box at the hind end, said scraper being adapted for closing the front end of the box when loaded, all as hereinafter fully described, reference being made to the accompanying drawings, in which Figure 1 is a longitudinal sectional elevation of my improved machine, and Fig. 2 is a plan view.

I mount a receiving and dumping box (L on suitable wheels, as I) and c, or it may be on runners, said box having the bottom (I pivdotted lines It 'i'.

The front edge of the bottom plate his preferably armed with strong points 7.: for penetratin g and breaking up frozen orhard-packed cakes of snow and dirt.

In front of the scoop is a rotary brush a or other form of rotary device adapted to brush or otherwise force accumulations of material on the front of the scoop back into the box, said brush or beater being in this instance geared by belts and pulleys with the wheels I) for being rotated thereby, but in case runners are used instead of wheels some other motor will be employed to rotate the brush. In this example I represent the brush as geared with both hind wheels forinsuring powerful act-i011 in case of deep and heavy snows or other conditions causing powerful resistance. To obtain requisite speed of the fan from the slow-moving wheels I), the primary belts Z are geared from the pulleys m on the wheels 1) onto the multiplying-pulleys 02, from which other belts 0 connect with small pulleys p on the brush shaft. Any wellknown provision may be made for differentia tion of the pulleys when turning from a straight course.

The brush is mounted in the extremities of arms q, pivoted in the axis 8 of the multiplying-pulleys n and 'rigidly connected with levers't, reaching forward in proximity to the drivers seat 11., suitably to be shift-ed for raising or lowering the brush, as may be required, and provided with latches 1- and notched bars 11' for setting it in position. For. raising the scoop and the bottom of the box, chains J; are connected with the front end of the scoop and rigged over pulleys 3 supported on standards .2, attached to the sides of the box and extending upward a suitable height, and therefrom the chains extend to a Windlass a,

mounted on the supporting-arms I), attached to the front portion of the box and reaching forward to the front gear of the truck, which may be of any approved kind.

Thewindlass has a ratchet c and a pawl c to set it for holding the front end high or low,

as required, and particularly for holding it in the position indicated by the dotted lines f to retain the front portion of the load while being conveyed to the dumping place; also, to hold the scoop and the bottom din the higher position, if need be, while dumping.

I claim 1. The combination of the receiving-box open at the front end and having means for moving it along the ground, also having the bottomand the tail-board adapted fordu mpopen at thelfront end, and having the bottom and the tail-board adapted fordum ping at the hind end," the scraper or scoophin'ged at the front end of the bottom and adapted for the front end to run along the surface of the ground,the vertically-adj 11st able rotarybrush or beater at the front end, of the box, and

means for raising the scoop'and the bottom of the box for dumping the load at the hind end substantially as described.-

3. The combination of the rece1vingbo i adapted for the front end to run along the ground, the Vertically-adj ustablerotarybrush or beater at the front end of the box, and the Windlass, chains and chain-carrying pulleys connected with the scoop for raising it and 20 the bottom of the box substantially as described.

Signed at New York city, in the county and State of New York, this 9th dayof February,

CARL G. OTTERSTEN.
